我在rails上的ruby上有一个实用程序，可以将文件上传到公共文件夹。通过提供该文件的链接，我可以下载该文件。
它在本地rails服务器上正常工作。
我将我的工作部署到了heroku。上传部分的工作原理。但是当我点击登录按钮时，它只是给出了错误
The page you were looking for doesn't exist.
You may have mistyped the address or the page may have moved.
在查看heroku日志时，我发现这是一个路由错误。
任何人请让我知道我错过了什么。因为我真的是初学者。
谢谢你，
更新 这是heroku日志

您的链接是/resume/Saghir%20Resume1.docx（/resume/Saghir Resume1.docx），但您在公共文件夹中说它是上传目录/public/resume/file_name？你是否将Rails设置为serve_static_assets？
正如@CodeGnome指出的那样，Heroku是一个短暂的文件系统，所以整个方法都是一个坏主意 - 通常你会为你上传的文件使用Amazon S3或类似的文件存储。即使您的路线正确，您上传的文件也可以使用不同的动态，因为您运行的是多个，或者因为您已重新部署。

Heroku有一个叫做Ephemeral文件系统的东西，所以在dyno的生命周期中它的运行进程可以使用它，但是这里存储的任何文件都会在dyno完成后被丢弃，所以是的它会保存文件，但之后它已删除，因此无法找到它。
一种非常常见的方法是使用paperclip和Amazon S3来处理/存储上传，这些也非常简单。这是一篇很好的文章，解释了如何执行此操作：https://devcenter.heroku.com/articles/paperclip-s3
